s claims. (c1. 1st- 64) The invention relates to railway cars in general, and-lntparticular to passenger cars especially o1' the streamline type and window structures therefor.

Itis anobject of thisinvention to provide an improved arrangement whereby window frames may be more conveniently and cheaply mounted in the sides of a structure.

Another object of this invention is the provision of a `cheap easily manufactured means whereby the .window frame maybe clamped in sealing relation to' the sides of the structure.

Another object of this. invention is the simpliiication of the attaching and .sealing means' for Window frames and of the cooperating car structure.

A still further'object iof this invention is the provisionKof a. strong' .yet light window structure adapted especially for streamlined or air conditioned cars. y l These and further objects will be apparent to one skilled in the art when taken in connection with the accompanying drawings in which Figure `1 is a sectional view of a car yside showing the window4 in relation'to the side wall; 'Mr

Fig. 2 is a close up section of the window shown in Fig. 1 and taken on line 2-2 of Fig. 3;

Fig. a is a. partial elevational view poking toing strip I8 isiinterlocked with the trim-supporting channel, the whole forming a curtain housing for. curta.ln 20 shown diagrammatlcally in Figs. 1 and 2.

The outer side plates are extended beyond the edges of the window opening and are weldedinf ward of their edges to the posts, top plate 8 and bottom plates 6 thus forming an extremely strong, frame rgidifying portion. Crimped metal straps D extend completely around the window'iopening and'are provided with outer plane'portions 22 and inner plane portions 24 connected by portions 2liv which in the instance shown are at right angles to the portions 22 and 24 although this is not necessary since any angle desired may be used. The side straps D have their outer portion 22swe1ded at W directly tothe side plate extension adjacentthe side posts while the top and bottom straps D have their outer portion 22 welded to the legs of the top plate 8 and bottom plate 6 respectively. It is. readily seen that simply by bending the straps D so as to make the connecting portions 2B of proper length the inner portions 24 will be placed in a single plane for the attachment of the window clamping member 28- or some other member if desired. The window clamping member is show-n as formed in ward a pair of windows fromthe inside of the car; Fig. 4 is a horizontal section through afcar side and taken on line 4-4 Fig. 3 and showing two forms of side posts; Q

Fig. 5 is a perspective view with parts broken away showing the construction at a lower corner of the window, and l Fig. 6 is a sectional view similar to Fig. 4 but showing a modication.

Referring now to the drawings inwhlch the invention is shown' as appliedto a railway 'car having side posts A and B which mayibe of the usual form orextend in an arch from side to side of the car to also form the carlines. The side posts "and carlines are covered with suitable outer plates 2 and inner plates 4.of any suitable shape or material desired. Window openings C are formed by. bottom plates 6 of-Z form extending `.between and welded to the side posts, and top plates 8 lof angular formation also extending between and welded to the side'rposts. The top Z form portion Mirto theupstanding leg of which is attached a Z member i4 carrying an interior trim-supporting channel I6. A decorative moldiour parts which-may be joinedat the corners by welding along lines 30 if desired or the entire member may be pressed from a single piece oi.'

metal. e

The .window supporting and clamping member 28 is formed with two opposed channel shaped portions 3l and 32 from the latter of which is extended a window vpositioning ange 34. Machine 'screws 3B extend through channel portions 3l and upon being tightened down will exert a pressure causing channel portion 32'to move outwardly thus clamping the window unit against the car side wall.

The window as shown comprises two panes of glass 38, preferably of the non-shatter type,

spaced apart by a spacer 40 andca'rried in a. channel 42 of rubber `or other` suitable materiaL The entire unit is self-contained and is preferably formed so that the space between the panes is sealed against ingress of moisture or any foreign matter, and upon being clamped by member 28 against the car wall it effectively seals the .car against ingress of moisture or foreign matter and also serves las an effective heat insulation due to the sealed double pane construction. This construction is purely representative since a 4single pane with its rubber channel comprising a unit 'u 56 IDW be used if desired. Curtain `guides 444,y window ledge 46 and trim 48 are applied to complete the window.

The side posts may be of the forms shown-in Fig. 4 in which post A is formed of a channel with its back welded to the plates with the open side closed by trim plates 50 while post B is formed of a channel opening outwardly and provided Iwith flanges 52 welded to the side plate and upon which will be mounted the strap yD. These posts are simply illustrative ofthe preferred forms, al-

though other forms may be used, and show the extreme ease and cheapness with which the uniplanar portion 24 for the clamping member may be formed by simply crimping an ordinaryv piece of strap metal the proper amount. l

In the modification shown in Fig. 6 the securing .member 54 is formed of angle metal and its proper adjustment is secured by either controlling the depth of the outwardly directed flange 56 or by the depth of welding metal used for its attachment.

Although the construction has been shown and described as applied to a rail car of the streamline construction it is obvious that it is equally applicable to other structures such as ships, metal buildings `and containers and is to be limited only in accordance with the appended claims.

What is claimed is: s

1. In a Window construction, the combination of top, bottom, and side members forming a window opening, means projecting beyond said members into said opening to thereby form a shoulder surrounding the opening, a Window unit Iin said opening, means attached to said shoulder and adapted to receive clamping and positioning means for said unit.

'2. Ina window construction, a window opening, metal members forming a shoulder surrounding the opening, a window unitin said opening adjacent the shoulder, means attached to said shoulder,- clamping members having laterally extending unit positioning flanges, and meansV cooperating` with said rst mentioned means and said clamping members to force the unit into engagement with lng, metal members forming a shoulder suropening adjacent the shoulder, means lcomprising angle shaped metal members having one ilange attached to said shoulder` and the other flange offset from and substantially parallel thereto, clamping members, and means cooperating with said offset ange and said clamping members to force the unit into engagement with the shoulder.

6. In a window construction, a window open- 'rounding the opening, a window unit in said ing, metal members forming a shoulder surrounding the opening, a Window unit in said opening adjacent the shoulder, means comprising angle Ashaped metalmembers having one iiange attached to said shoulder and the other ange oiset from and substantially parallel thereto, clamping members having laterally directed unit positioning flanges, and means cooperating with said oiset ange and said clamping members to force the unit into engagement with the shoulder.
